ChemistryPrinciples of Instrumental Analysis(a) Interpretation: The formula of the complex should be determined. Concept introduction: In photometric titration, absorbance of the solution is measured to determine the endpoint of the titration. This is based on the theory that the absorbance of a solution is directly proportional to the concentration of analyte. A graph is plotted between absorbance versus volume of titrant added.Start your trial now! First week only $4.99!*arrow_forward*

Interpretation Introduction

**(a)**

**Interpretation:**

The formula of the complex should be determined.

**Concept introduction:**

In photometric titration, absorbance of the solution is measured to determine the endpoint of the titration. This is based on the theory that the absorbance of a solution is directly proportional to the concentration of analyte. A graph is plotted between absorbance versus volume of titrant added.

Interpretation Introduction

**(b)**

**Interpretation:**

The molar absorptivity of the complex should be determined.

**Concept introduction:**

The Beer-Lambert Law is:

where,

A − absorbance

l − length of the solution light passes through (cm)

c − concentration of solution (mol/L)
